Ukraine Must Keep up Fight Against Corruption: Biden

Ukraine's government needs to investigate and prosecute corruption at all levels and implement difficult political reforms to retain the support of the United States, U.S. Vice President Joe Biden said on Wednesday.
The U.S. government has given Kiev $470 million in economic assistance and signed two loan guarantees, each worth $1 billion, since pro-Western parties took office in Ukraine more than a year ago.
Another $1 billion U.S. loan guarantee has been promised by the end of the year, but is contingent on reforms, Biden said in a speech at the Brookings Institution think tank.
"Ukraine needs to use all the tools at its disposal to limit the ability of the oligarchs to abuse their market position or exert pressure on government officials," Biden said.
